Why is prayer important for Christians according to Job's experience?

Job’s experience highlights the significance of prayer as a vital expression of a believer's heart. As Job laments, 'my eye poureth out tears unto God' (Job 16:20), it demonstrates that genuine prayer often transcends words, emerging from deep sorrow and longing for divine intervention. Prayer is the 'soul's sincere desire,' allowing believers to pour out their innermost troubles and seek refuge in God. Furthermore, Job's assertion for someone to plead with God emphasizes the Christian belief in the need for an intercessor, ultimately pointing to Christ as the ultimate Mediator who enables believers to bring their petitions before God with confidence.
